Abstract: © 2016 Elsevier Inc. The structure of λ-constacyclic codes of length 2sover the Galois ring GR(2a,m) is obtained, for any unit λ of the form 4z−1, z∈GR(2a,m). The duals codes and necessary and sufficient conditions for the existence of a self-dual λ-constacyclic code are provided. Among others, this structure is used to establish the Hamming, homogeneous, and Rosenbloom–Tsfasman distances, and Rosenbloom–Tsfasman weight distribution of all such constacyclic codes.
